Yea....... agree here.
>no persistence of storage inside the container, unless you commit the container to a new image or add volumes which are slow bullshit too
What are you persisting?
The only time I've used this feature is for DB persistence in dev. I have yet to see volumes used in production.
>docker images are bloatware
We use both Go and Node docker images at my day job. Node image sizes are < 60 mb. Go image sizes are < 30 mb.

Listen, docker is programmers first container. it's good enough for most things. Are there better containers out there? Yes--Mesos. Do most people need a big ass data-center abstraction framework? No.
If you're going to start a docker hate thread at least show that you've used it for more than 5 minutes and have thoughful criticisms.
I hate docker because my company works from the mindset of 'how can we take X and jam it into a docker container?' instead of will x benefit being containerized.

that's honestly the only real problem I have with docker is it's misuse. I ran into the same thing all the time with people wanting to do things like run a Solr cluster in docker. It makes no sense to store continually growing indexes in a container that's a recipe for disaster.

lmao good luck keeping your job in the next 5 years. almost every big company is containerizing their systems and applications
